| 摘 要： | 哈母白祖熔岩铁矿位于大红山铁铜矿区东部.矿体均赋存于大红山群红山组变钠质熔岩、绿片岩中,呈层状、似层状、透镜状产出,矿石以磁铁矿为主。矿床的形成与古元古代的海相基性岩浆喷发作用关系密切,具有火山喷溢和火山喷发沉积的特点,后期又经历了区域变质作用的改造,是经过多次地质作用而形成的多成因复合型矿床,成因类型初步判断为火山岩浆喷溢-喷发沉积-变质改造复合成因矿床。

Geological characteristics and genesis of Hamubaizu lava type iron deposit in Dahongshan of Yunnan |
| |
| Abstract: | Hamubaizu lava type iron deposit is located in the east of Dahongshan Cu-Fe mining area,and the orebodies occur in the metamorphic sodic lava and greenschist of Hongshan Formation of Dahongshan Group.The orebodies occur as layered,stratoid and lenticular in form and the ore are mainly magnetite.The formation of the deposit is closely related to the eruption of Paleoproterozoic marine basic magma,and the deposit is characterized by volcanic overflow and volcanic eruption-sedimentation.After the renovation of regional metamorphism in late stage,it becomes a poly-genetic complex deposit which has experienced many geological processes.In a preliminary estimate the deposit is a complex deposit formed by volcanic magma eruption-eruption sedimentation-metamorphism reformation. |
